Y Specification of Letters Patent. Patented March 17, 1908.

Application filed. ay s, 1901. Serial No. #172,593.

To all whom it may concern;

Be it known that L ALFRED W1LKI N,.a citi- .zen of the United States,and a resident of 'the city of New York,

ough of Richmond, in the county of Rich mond and State of New York, haveinvented a new and Improved Preserving Jar, of

which the following is a full, clear, and exact description.

.Thepbject of the invention is the elimination of recognized defects inthe preservmg ]8.I or vessel as ordinarily used, among which, for exam1e, are the use of rubber for 'valves and gas ets, which furnish nestinplaces for the pripagation of germs; the 18.01% or the escape of air orother gases from the jar or vessel during the canoperation; thelikelihood of-the bacteria of t e air finding access to the interior ofthe vessel and the difliculty of removing the cap from the vessel whensealed.

I am enabled to overcome the above objections ymy invention, oneembodiment of which is hereinafter disclosed.

Reference is to be had to the'accompanying drawings forming a part ofthis specification, in which similar characters of refer ence indicatecorresponding parts in all the" es. Figure 1 is a central, verticalsection through the preferred forin of my invention;

g. -2 is a plan of the c ap or cover for the vessel'; Flg. 3 is aninverted lanof the same;

4 1s a plan of the ve'ssei is a view of a disk of paper or othersuitable material which is employed in the preservoperation; 1 I heinvention comprises a' ar or vessel body 1 of suitable size and shape,that shown being uniformly cylindrical on the exterior and, constructedwith a contracted -portion 2 at its upper end forming the jar than theouter wall and shown in Fig. 1,is constructed with a with a thickenedthe-bottom edge thereof. I 'the'cap fi is preferably formed slig tlycon-' v neck. In the top face of this neck, an annular groove 3 isformed, the inner wall 4 of which is made somewhat higher I provides aseat for receiving a cap or cover 5. This cap, as best flange 6 on itsunder face, said'flange being exteriorly threaded and entering thegroove3 when the ca is seated in osition'. I The dimensions of t egroove andan e are such that the flange will be separate from the walls of thegrooveat both sides as well as at The 'to face of New Brighton, bor

' ter to be or jar, and Fig. 5

into the groove 3 formed in the jar. vterior of the or; depression 7when the capis in place, through a perforation SQpassing through thecenter of the cap, sai perforation being closed by a disk 10 of pa er orother suitable material, shown in detai in Fig.5.

In the use of the jar, the fruit or other matcooked in't e ars or in aseparate vessel, in the latter case bein placed in the jars until theyare well filled, the cap 5 quite hot is then Ia'c'ed in ig'. -1". T edisk 10 should then be dipped in. araflin' or other similar sealingmaterial and placed in the cup 7 over-the top of the perforation 9. .Thesealing mixture, which araflin,. is I thereafter- 'while" 1s ordinarilyuite'hot and'm a'liquid state, poured into .t e on 7 and overflowsthrough the grooves 8 and lls the groove 3 at the inside and outside ofthe flange 6 on the cap. Steam, air

or other gases rising from the fruit while the parafiin in' thecup 7 isin the liquid state, passes through the perforation 9 under the valve 10and esca es. As there is a larger portion of materia in the cap aroundits center than at the circumference of the cap, the paraffin in the on7 will remain in the iquid condition longer t an elsewhere. When thetemperature lowers, theparaflin hardens first in. the annular groove 3andthereafter in the on 7, leaving the jar hermetically sealed. lghsmall nail or similar device is thrust through the parafiin into thevent-cup and through the perforation 9, .thus admitting the*8.l!. By nowslightly warming the cap, the paraffin loosens its hold on the thread.of. .the flange, which may then be easily screwed ofi. c It is evidentthat the invention as illustrated in the accompanying draw ng and ashereinbefore described 1s=s1Isce tlble of numerous modificationsfallingwit the scope of"the annexed-claims.

Having thus described my invention I claim as Patent:

- 1. A'preserv'ing bodyhaving an annular groove 1n its upper end, and acap seated over said'body aving a-threaded' flan e projecting into saidgroove, said threade flange being externallyical and construct-ed with avent-cup or depression 7 atits center, from which lead :a 3 number ofradiating grooves or channels" 8;.

The in-' jar communicates with the cup Y reserved, after being properlyI osition on each jar, as shown in en the jar is to be opened, a pin,

jar or vessel, comprising a and internally spaced from the walls of saidgroove whereby when the groove is filled with a sealing material it willenveldp said flange both .exteriorly and interiorly'.

2. A preserving jar or vesselcomprising a body having an annular groovein its upper end, a cap seated'over said body, having a recess forming avent-cup which co'mmunicates with said groove, and a threaded flange 5.A preserving jar or vessel comprising a body having an annular groove inits ,upper end, a cap seated over said body having a recess forming avent-cu which communicates with said groove, a ange projecting from saidinto said groove, and a seali materia substantially filling said cup angroove.

6. A preserving jar or vessel comprisinga projecting from the cap intosaid groove, body having an annular groove in its upper said threadedflange being externally and inend, a ca seated over said body having areternally spaced from the walls of said groove. cess wit a erforatedbottom'forming a 40 whereby a sealing material introduced into vent-cuan a flange projecting into said the groove will envelop the flange atboth groove i rom said ca said flange being exsides i ternally andinternal y spaced from the walls 3. A preserving jar or vesselcomprising a of said groove whereby a sealing material inbody having agroovesurrounding the neck troduced into the groove will envelop thethereof, a cap seate'd over the neck" of said flange at both sides, andsaid ca havin body, having a recess forming a vent-cup radial channelsor grooves leading rom sai which communicates with said groove, and aprojecting portion formed on the cappassing into said groove.

4. A preserving jar or vessel, comprising a, body having an annulargroove .in its upper and, a ca seated oversaid body having a threadedange projecting into said groove, end a" sealing material said grooveand entering the threads on sai 'flange.
